SPECIFICATION forming part of Letters Patent No. 320,636, dated June 23,1885.

Application filed March 6, 1885.

T0 aZZ whom it may concern.-

Be it known that we, HENRY DAVENPORT and GEORGE DAVENPORT, both ofSomerville, in the county of Philadelphia and State of Pennsylvania,have invented a new and Improved Reflecticon, of which the following isafull, clear, and exact description.

The object of our invention is to provide a new and improved apparatusfor reflecting pictures, &c., on a screen or white wall.

The invention consists in the combination, with a box having a mirror onthe inner surface of each end, and two mirrors on the innor surface ofthe front, of a lens-tubein the front and a picture-holding slide on theback.

The invention also consists in various parts and details andcombinations of the same, as will be fully set forth hereinafter.

Reference is to be had to the accompanying drawings, forming part ofthis specification, in which similar letters of reference indicatecorresponding parts in all the figures.

Figure 1 is a rear view of our improved refleet-ion. Fig. 2 is alongitudinal sectional elevation of the same on the line 1113/, Fig. 3.Fig. 3 is a cross-sectional elevation of the same on line :0 0c inFig. 1. Fig. 4 is a plan view of the same.

On the inner surface of each end B of a box, A, a concave reflector ormirror, 0, is secured, and on the inner surface of the front D a concavemirror or reflector,'E, is secured at each end in such positions as toconcentrate the light upon the picture at N Between the mirrors E atube, F, projects inward from the front D, and in the same a slidingtube, G, is arranged, holding a double convex lens, H.

A rod, J, extends from the inner tube, G, up to the top of the back K ofthe box, and is used for focusing the lens'tube G. In the box A twolamps, L, or other lights such as calcium'llghts,elcctriclights, &c.areplaced between the mirrors 0 E at each end.

A detachable funnel, M, is arranged above each light on the top V of thebox, which top has a curved under side which is silvered and polished ormade bright in any other suitable manner to reflect the rays of light. Aventilating-opening,V, is arranged in the said top, and is provided witha hood, V, which ventilatingcpening permits the hot air to escape. Thefront corners of the box are rounded. A

(No model.)

doors Q, which can be held closed by pivoted buttons It.

A door, S, is hinged on the front of the box below or at either side ofthe tube F, and on the inner side of the said door a flat mirror orreflector, T, is secured. The box has a perforated bottom, U, to admitair.

The pictures W are placed in the sliding piece 0, and held in place byclosing the doors Q, and then one picture is shifted to appear in theopening N. The light from the two lamps is reflected by the mirrors 0 Eupon the picture, and from the same through the lens H upon a screen orwall. By means of .the mirror T it can be reflected upon a wall ateither side of the box or upon the ceiling.

The reflection of the picture on the wall or screen can be enlarged moreor less by moving the reflecticon to or from the screen or wall. Thepictures never become heated sufficiently to injure them, and may remainin the apparatus for hours without being destroyed. Any opaqueobject-such as a photograph, chromo, drawing, &c.can easily be reflectedupon the screen in any desired size, and all parts will be clear anddistinct, so as to be seen clearly and distinctly by a large audience.

Having thus described our invention, what we claim as new, and desire tosecure by Letters Patent, is-
